HOSE-BINDER.

SPECIFICATION forming part of Letters-Patent No. '77 3,965, datedNovember 1, 1904.

Application filed June 24, 1904.

To all 1071/0777] it pea/y concern:

Be it known that we, JOHN J. MoIN'rYRE and HERBERT BAGSHAW, citizens ofthe United States, residing at Hartford, in the county of Hartford andState of Connecticut, have invented certain new and useful Improvementsin Hose-Binders, of which the following is a specification.

This invention relates to hose-binders, and has for an object to providean improved and efficient device of this character.

In the drawings accompanying and forming a part of this specification.Figure 1 is a central longitudinal section of the binder made inaccordance with the present improvements and shows a broken-off portionof hose held in position thereby. Fig. 2 is a similar view of two of themembers of the hose-binder disconnected. Fig. 3 is an enlarged detail ofthe parts shown in Fig. 2; and Fig. 4 is a view similar to Fig. 3, butshowing the parts in their assembled position.

In the drawings the hose (designated in a general way by 7) is shownclamped between an expander member 8 and a binder member 9, each ofwhich is provided with annular retaining-abutments 10, comprising aseries of teeth or ridges whereby the hose is securely held in position.The hose herein illustrated is supposed to represent an outer fabricportion 11 and an inner rubber lining portion 12. The latter beingreadily puncturable, it is essential that the binding of the hose bedone in such a manner that the lining will be maintained inviolate, forif the binding or other means produces a rupture of the lining the hosewill break and the binding will be ineffectual. In drawing the bindingmember 9 over the expanded end of the hose and the expander it isdesirable that the expander be self-centering to a certain extent insome instances and that the same does not rotate upon the hose or withinthe same.

The expander is shown carried by the coupling member or block 13 and ashaving a double ball-joint connection therewith. The coupling member isshown as having a ballsocket 1 1, in which a bearing .15 of the expandermay seat, and the expander is shown Serial. No. 213,928. (No model.)

as having a ball-seat 16 to receive a bearing 17 of the coupling member,whereby after the parts have been assembled there will be a doubleball-joint provided between the expander and the coupling member. Thefaces 14 and 16 are oppositely curved, as are also the faces 15 and 17,whereby it may be that in practice the face 15 will lie against the face14 at one side of the device and the face 16 will lie against the face17 at the opposite side. This organization will give a comparativelylarge amount of self-centering and ball-joint action. The parts maybemade in any suitable manner and assembled. The lip 18 may be madeslightly larger in diameter than the lip 19 and the two parts assembledby being pressed together, after which any deflection of the innermember may be rectified by driving a mandrel within itthat is, assumingthat the amount of yielding was greater than the amount of yieldabilitywhich the metal would overcome by its inherent elasticity. In someinstances to permit the expander to have a self-centering action andgive the fullest advantage of the double ball-joint an amount of playindicated by the space, as 20, may be provided between the membersconstituting such ball-joint, whereby a certain amount of movement maybe had. The amount of space of course will be dependent upon the varioussizes of hose and the uses to which the binder is to be put.

The binding member 9 in the present instance is shown as carried by acoupling-nut 21, having screw-threaded engagement with the coupler 13,whereby after the expander has been inserted in a hose at its end thebinder may be. drawn up over the expander and such end of the hose, andany turning or twisting of the nut, which would otherwise have atendency to turn the expander within the hose, will be prevented by theswivel connection between the expander and the coupler from producing aturning of the expander, and in turning up the binder it may be that thebinder will not turn upon the hose, in which case the hose and theexpander will move in unison with the binder until the parts assumetheir final position. The ball-joint connection and the swivelconnection prevent the rupture of the hose in the process of assemblingthe parts upon the hose and also give a self-centering action to theexpander, which will prevent undue pressure upon certain parts of thehose.

Having thus described our invention, we claim- 1. A hose-bindercomprising a couplingblock, an expander swiveled thereto and having adouble ball connection therewith, and a binder adapted to screw onto thecoupling block and overlie the expander.

2. In a hose-coupling the combination with a binder, a nut integrallycarrying the same, a member on which the nut may screw, and an expandercarried by such member by means of a double ball connection.

3. Ahose-bindercomprisingabindingmember, an expander, a block carryingthe binding member and having a double ball connection with theexpander.

4. The combination with a binder, of an expander, means to force theexpander into the binder and having a swivel self-centering connectiontherewith.

5. In a hose-binder the combination with a member to support the outsideof a hose, a member to expand the hose within said sup porting member,and a member having screwthreaded engagement with such outside memberand having a flange engagingaflange upon the expanding member towithdraw the same from the hose, and a self-centering joint between itand such expanding member to force the same into the hose.

6. In a hose-binder the combination with a member to support the outsideof a hose, a member to expand the hose within said supporting member,and a member having screwthreaded engagement with such outside memberand having a flange engaginga flange upon the expanding member towithdraw the same from thehose, and a self-centering double balljointbetween it and such expanding member to force the same into the hose.

7. In a hose-binder, the combination with a member to support theoutside of an end of a hose and having an interiorly-screw-threadedsleeve, an expander, means having screwthreaded connection with saidsleeve and carrying the expander by a double ball-joint having facescurved in opposite directions.
